The manual titration station STI consists of

• a burette with digital display and
• a magnetic stirrer with exactly fitting holder for a conical flask

A visual screen serves as a neutral background and enables the user to determine the colour change at the end of titration exactly. In this way he always carries out his titrations under similar optical conditions. This improves the accuracy and reproduciblity of the results.
This is also aided by the exact positioning of the vessel in the holder on the upper side of the magnetic stirrer. The wings of the screen also protect against dazzle from the sides. Delivery without bottle.
